Introduction of edible rapeseed oil press machine

1. Method of edible rapeseed oil seeds pretreatment and prepress line

Cooking rapeseed oil seeds press production line includes two parts, one is pretreatment line, the other is oil seed press machine, cotton seeds oil squeezing machine.

Pretreatment part is used for cleaning and adjusting texture of the materials , it can improve oil yield rate, reducing breakdown of the machines. General speaking, the pretreatment machines include Magnetic drum, Cleaning sieves, Sheller, Crusher, Flaking roll, Cooker, Softening pot , Puffing machine and so on. After pretreatment, the materials will be sent to oil expeller, then the crude oil got. Different materials have different pre-press methods. We usually collocate proper press line according to the customers' materials.

2. The difference of pressing and extraction(leaching):

Squeezing method due to the yield is low, so the raw material for squeezing must be seeds of high oil content, and itself is probably oil crops; Due only to squeeze at the same time, the residual oil in the cake is high, so the modern enterprise in order to save resources, the pursuit of efficiency of cases will be to squeeze the oil cake with leaching rule of oil again

3. Introduction of rapeseeds cake solvent extraction line

The whole rapeseeds oil extraction machine workshop is selected on the base of safety, reliable, energy-saving, less fault, easy maintenance, and long using life, adopting world advanced technology and equipment to achieve the best process effect.

Process flow:

The material(for pretreatment) is sent to the extractor by the airtight packing auger. The mateiral will be sprayed for extraction by the solvent(Hexance) or mixed oil after they fall into the extractor. The wet dreg(after dripping), falling into the conveyor and be sent to the evapo-separated machine. After steaming, baking and desolventizing, the dreg will be sent to the dreg storehouse. Mixed oil after extraction enters into the first and second long tube evaporator for seperating the steam and solvent, and then flow into the stripping tower for desorption the remaining solvent of crude oil. The extracted oil from the last process will be sent into the crude oil tank for refining plant. The solvent vapors from the extractor, evapo-separated machine, evaporator, stripper tower will be recycled in the cooling system. The solvent after cooling will be collected in the fresh solvent tank for reusing in the process.
